Water circulating pump power consumption is than larger in power plant, it will usually account for 10% of station service or so, and what is be becoming tight in energy day is big
Under environment, it is necessary to carry out reducing energy consumption to circulation.It is being distributed test run initial stage and is referring to the later stage in maintenance stage
It is not required under water circulating pump running situation, now only each subsidiary engine needs the cooling water that recirculated water is provided, water pump is installed in startup additional, can be with
Meet each subsidiary engine safe operation.The consumption of electric energy thus greatly reduces, the economic benefit of power plant is improved.
The content of the invention
There is provided a kind of simple in construction easy to operate, and with circulation transformation side that is energy-saving, increasing economic efficiency
Case, i.e., in distribution test run initial stage and maintenance later stage in stage, by running improved system pipeline, meet each subsidiary engine and transport safely
OK.
System schema 1：Single flow recirculating cooling water system is transformed, such as Fig. 1, in cleaning water system two-way main pipe
On, two-way pipeline is drawn respectively, pipeline correspondence is connected on one, in No. two machine recirculated water main pipes.The system operation after transformation is met
During condition, start corresponding flushing water pump, stop corresponding water circulating pump, close all circulation water entrances of condenser electronic
Door, opens certain angle by the backwater electrically operated gate of recirculated water, meets the normal operating pressure of recirculated water.Each road is kept to remove heat exchanger
And the valve of subsidiary engine meets the normal operation of each subsidiary engine equipment in opening.
System schema 2：Tower circulation is transformed, such as Fig. 2, before recirculated water water inlet electrically operated gate, circulation
Water inlet channel is drawn all the way close to bottom, installs the caliber 219mm of pipeline additional.It is connected to butterfly valve on the pipeline of closed water cooler
Afterwards.One circulating water pump is installed on pipeline is installed additional, the front and rear of pump installs manually operated door additional.The pump type selecting should meet each auxiliary equipment
Cooling water, typically select power be 0.3-0.4MPa water pump with regard to condition can be met.In system operation conditions after meeting transformation,
The circulation water entrance electrically operated gate of condenser is closed, oil cooler Inlet and outlet water butterfly valve, the cold cooler of power generation air, water water cooler enter
Backwater butterfly valve, closed water cooler water inlet butterfly valve, closed-up water backwater butterfly valve is opened, circulating cooling unit fixed on water pump suction manually operated door is beaten
Open, start cooling water pump, open the outlet manually operated door of pump.Now closed water cooler normal work, and each subsidiary engine can be met
Normal operation.
